Dr Katharine Aitken has both a private and an NHS practice at The Royal Marsden. She is a Consultant Clinical Oncologist, specialising in radiotherapy treatment for upper and lower gastrointestinal (GI) and hepatopancreatobiliary (HPB) cancers.

She graduated from University College London Medical School in 2003, winning the Hutley Atchinson prize for best clinical performance. Her specialist oncology training was completed at The Royal Marsden and Guy’s and St Thomas’ Hospitals following which she undertook a research degree at The Institute of Cancer Research.

Her research centred on the use of stereotactic body radiotherapy (SBRT) for the treatment of oligometastatic disease. Her research fellowship included time at Memorial Sloan Kettering Hospital in New York to further her technical skills in GI radiotherapy. She was appointed as a Consultant Clinical Oncologist in the GI unit at The Royal Marsden in 2015.

Her research interests include the use of radiotherapy for primary and metastatic liver tumours and pancreatic cancer. She is the clinical lead for novel developmental work on Magnetic Resonance (MR) guided adaptive therapy for pancreatic cancer. She is regarded as a national expert in liver SBRT and acts as a technical advisor on radiotherapy quality to NHS England’s Commissioning Through Evaluation (CTE) program for SBRT.
